Lesson 2 Air pressure is the air's push

Lesson 3 Measure the whole weather picture
Grade 3's three instruments recalled; a barometer measures air pressure in millibars, a hygrometer humidity as a percent, an anemometer wind speed in miles per hour; the table grows three columns; Monday's row filled; the week's table

Lesson 5 Which way is the data going?
Compare the first dot with the last: the temperature rising, the air pressure falling, the humidity staying level; Micah's rain barrel, one dip, still rising
